DTC P0500:00

Vehicle speed signal circuit malfunction

DETECTION CONDITION

•  Under the following conditions, the vehicle speed signal input from DSC HU/CM is incorrect for 10 s:

―  Engine is running.

―  Battery voltage is 8 V or more.

―  Vehicle speed is 16 km/h {9.9 mph} or more.

―  There is no difference in speed between turbine/input shaft speed sensor and output shaft speed sensor.

Diagnostic support note

•  The check engine light illuminates if the TCM detects the above malfunction condition during the first drive cycle.

•  The automatic transaxle warning light does not illuminate.

•  PENDING CODE is available.

•  FREEZE FRAME DATA is available.

•  The DTC is stored in the TCM memory.

FAIL-SAFE FUNCTION

•  Inhibits learning control.

•  Inhibits neutral idle control.

•  Inhibits i-stop control.

•  Inhibits AAS.

POSSIBLE CAUSE

•  DSC HU/CM DTC is stored.

―  ABS wheel-speed sensor malfunction

Diagnostic procedure

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA/SNAPSHOT DATA HAS BEEN RECORDED • Has the freeze frame data/snapshot data been recorded on the repair order?	Yes	Go to the next step.
1		No	Record the freeze frame data/snapshot data on the repair order, then go to the next step.
2	VERIFY RELATED SERVICE INFORMATION AVAILABILITY • Verify related Service Information availability. • Is any related Service Information available?	Yes	Perform repair or diagnosis according to the available Service Information. • If the vehicle is not repaired, go to the next step.
2		No	Go to the next step.
3	VERIFY STORED DTC IN DSC HU/CM • Perform the DSC HU/CM DTC inspection using the M-MDS. (See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)].)
3		No	Go to the next step.
4	VERIFY DTC TROUBLESHOOTING COMPLETED • Clear the DTC using the M-MDS. (See ON-BOARD DIAGNOSTIC SYSTEM DTC INSPECTION [FW6A-EL].) • Perform the following procedure to ensure that the DTC has been resolved: 1. Drive the vehicle for 10 s or more under the following conditions: • Battery voltage: 8 V or more • Vehicle speed: 45 km/h {28 mph} or more • Perform the DTC inspection using the M-MDS. (See ON-BOARD DIAGNOSTIC SYSTEM DTC INSPECTION [FW6A-EL].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See ON-BOARD DIAGNOSTIC SYSTEM DTC TABLE [FW6A-EL].)
4		No	DTC troubleshooting completed.
